ASUS RT-BE88U review

Wi-Fi Specifications

The BE88U uses 2.4GHz for longer reach and devices such as smart plugs, with 5GHz offering more speed nearby. Its 160MHz channels can carry more data than 80MHz channels, although they need more clear spectrum. A crowded apartment may be better served by a narrower channel.

Phones and laptops with 6GHz support can still connect on a lower band, but they miss out on the extra spectrum their radios could use. The BE88U also stops short of the 320MHz channels available on some other Wi-Fi 7 routers.

The BE7200 rating combines advertised link rates of 5,764Mbps on 5GHz and 1,376Mbps on 2.4GHz, across four streams per band. Those are radio ceilings, not file-transfer speeds for your laptop. Its own radio, Wi-Fi overhead and other traffic all reduce what is available.

Wireless Performance

Multi-Link Operation, or MLO, gives compatible Wi-Fi 7 devices more flexibility by establishing links over both bands. Depending on the client, traffic can switch between them or use both. That can help when one band is busy, though it does not give every device the sum of both bands’ advertised speeds.

A busy evening still means sharing airtime: downloads, video streams and calls compete on the same wireless channel. The BE88U’s many ports offer a straightforward way to ease that competition. Put stationary devices such as a desktop or console on Ethernet, and their downloads no longer use Wi-Fi. They still share your internet connection.

Walls, nearby networks and the antennas in your phone or laptop all affect the connection. Give the BE88U an open, central position where you can. Chasing the highest link rate is less useful than getting a decent signal in the rooms you actually use.

Wired Connectivity

I like the flexibility of using both 10G connections for a workstation and NAS. Put the internet connection on the 2.5GbE WAN port and both are available locally, leaving three 2.5GbE ports for other devices. Fast photo or video transfers between those machines don’t need a matching internet subscription.

The four gigabit ports suit a television, printer or console with gigabit Ethernet, while the faster ports can serve newer computers and wired rooms. Nine RJ45 sockets plus SFP+ give you room to spread out. Your adapters, cabling and storage still need to keep up with the port speeds.

SFP+ is the connection to plan around. It takes a compatible direct-attach cable or transceiver, rather than an ordinary Ethernet plug. A second copper 10G device needs a suitable SFP+-to-RJ45 module; check ASUS’s compatibility list before buying one. A matching optical connector also does not guarantee compatibility with your internet provider.

Software & Features

Guest Network Pro lets you give visitors or smart-home devices a separate network, and VLAN controls extend that grouping to wired connections. Keeping smart plugs away from your work computer or family NAS is a useful option. Set the access permissions deliberately: blocking local access can also stop your phone from finding those devices.

AiMesh lets you add compatible ASUS units for coverage in more rooms. If you can cable the units together, their link back to the router leaves the radios free for wireless devices. Wireless mesh is more convenient when cabling is impractical, but uses some of that wireless capacity.

WireGuard can provide a way back into your home network while you are away—for example, to retrieve a file from a NAS. You’ll need to configure your phone or laptop, and ASUS’s server setup requires a reachable public WAN IP from your provider. The router can also act as a VPN client for selected devices.

USB storage sharing is handy for household documents or media, though I would not buy this router as a fast NAS replacement. Dong Knows Tech’s 2024 portable-SSD test over multi-gigabit Ethernet generally stayed below 200MB/s for reads and writes. ¹ That is a historical test result, not a fixed limit for every setup.

Security & Firmware

AiProtection Pro includes malicious-site blocking, intrusion prevention and a router security assessment. It is a useful extra, alongside a strong administrator password and keeping remote-access services off when you do not need them.

Firmware deserves attention too. ASUS’s release notes include security fixes and a correction for DNSSEC-related internet dropouts. Check for updates during setup and periodically afterward. We have not established a guaranteed future support deadline for this US model.

Alternatives

If most of your devices are wireless, the ASUS RT-BE92U deserves a look. Its 6GHz band and 320MHz support give compatible clients more wireless options. You still get one 10GbE and four 2.5GbE ports, but lose the BE88U’s second 10G interface and larger port count. The extra band is most useful within good reception range; it will not solve every coverage problem.

You may not need a new router at all. A suitable switch adds ports to a supported router you already like, while a wired access point can bring Wi-Fi closer to a troublesome room.

Verdict

The RT-BE88U’s appeal is its room for a substantial wired network, backed by flexible software and dual-band Wi-Fi 7. For a home with fast storage and several wired rooms, that is an attractive combination. If those extra connections would sit empty, the missing 6GHz band becomes harder to overlook.
